Behavioral state, heart rate, and respiration were monitored during heelstick procedures in samples of healthy, term neonates (N = 48) and preterm neonates treated in minimal care (N = 48) and intensive care (N = 48) nurseries. The treated infants who were given pacifiers spent significantly less time fussing and crying during and following the heelstick procedures. Physiologic arousal was monitored in both preterm groups but was attenuated only in the preterm infants who received pacifiers (minimal care group). As similar amounts of sucking were observed in both preterm groups, the inconsistency in treatment effects on behavioral and physiologic arousal was interpreted as a lack of cardiac-somatic coupling in the neonate in intensive care. Results suggest that nonnutritive sucking during heelstick procedures may attenuate behavioral distress in all neonates and physiologic arousal in neonates with less severe postnatal complications.
在足跟采血操作过程中，对健康足月儿样本（N = 48）以及在最小护理（N = 48）和重症护理（N = 48）育婴室接受治疗的早产儿的行为状态、心率和呼吸进行了监测。接受安抚奶嘴的治疗婴儿在足跟采血操作期间及之后哭闹和烦躁的时间明显减少。对两个早产组的生理唤醒情况进行了监测，但仅在接受安抚奶嘴的早产儿（最小护理组）中生理唤醒有所减弱。由于两个早产组观察到的吸吮量相似，因此对行为和生理唤醒的治疗效果不一致被解释为重症护理中的新生儿缺乏心身耦合。结果表明，足跟采血操作期间的非营养性吸吮可能会减轻所有新生儿的行为困扰以及出生后并发症较轻的新生儿的生理唤醒。
